"My Filters" section of the settings is pretty bugged on Android

[Palloxin]

Prerequisites

• I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
• This is not a support issue or a question. For any support, questions or help, visit /r/uBlockOrigin.
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.
• I checked the documentation to understand that the issue I am reporting is not normal behavior.

I tried to reproduce the issue when...

• uBO is the only extension.
• uBO uses default lists and settings.
• using a new, unmodified browser profile.

Description

1. the text selector does what it wants only in this extension (see the video)

2. it is hard to delete lines of code, i try to use the delete button of the keyboard and lines are not delete.

@ghajini I tried it, but the themes are ugly. I used another keyboard called Florisboard, highly customizable keyboard open source, and the problems are still there

Using anysoftkeyboard

I can reproduce your description point 1 and i guess you want to copy the filter, just click on gutter start of filter, that serves the purpose

& for your other problems try disabling show suggestions & auto-capitalization feature in aosp keyboard settings...

@ghajini i forgot to say that your keyboard doesn't bug "my filters" code editor. anyway the bug is still there , and it happens with the most used keyboard on android. thus i would say it is a problem

@BlazeFTL ok, I can reproduce this one. Not related to toolbar position for me. I think it happens when uBO is restoring the cursor position to the bottom of a long list of filters. Does not happen for 3-4 filters, but after restoring my backup with hundreds of lines, then placing the cursor at the bottom, I was able to reproduce. I was able to fix by putting the cursor in the first line, close the tab and open again. This does not always work, probably because the cursor position is saved after a delay.

@gorhill ?

If it can help i had a similar problem on another app with the cursor position doing weird stuff and it happened only on miui
LNReader/lnreader#654
This has been fixed and maybe it can help.
In that issue a guy with A12 and miui 13 had the same problem so i guess there is a link.

Yes Problems Can Increase Depending On Android Version Or Rom...#2805 The Video Attached There Was a A11 Rom But 95% Issues Was Solved On A13 Rom

I can still reproduce in Firefox 121 Mobile & uBO 1.54 all the issues OP reported, in two different phones & different versions of Android, one with MIUI (Xiaomi Redmi Note Series) and the other without (Samsung Galaxy S Series), which means the issue is not specific only to MIUI, and Samsung keyboard is broken as well.

All the issues repored here cause managing My Filters in uBO Mobile be very cumbersome.

Also I'm aware that the issues are caused by CodeMirror rather than uBO: #1716 (comment) + #2805 (comment), but if the issues will be fixed in CodeMirror, uBO will need to switch to the new version of CodeMirror.
